DS22263B-page 1 Features • Position Sensorless BLDC Drivers (No Hall Sensor Required) • 180° Sinusoidal Drive, for High Efficiency and Low Acoustic Noise • Support 2V to 14V Power Supplies • Speed Control Through PAM and/or PWM • Built-in Frequency Generator (FG Output Signal) • Built-in Lock-up Protection and Automatic Recovery Circuit (External Capacitor not Necessary) • Built-in Over Current Limitation and Short Circuit Protection • Built-in Thermal Shutdown Protection • Thermally Enhanced SOP-8 Package for MTD6501C and MTD6501G (Maximum Output Current – 800 mA); • MSOP-10L Package for MTD6501D (Maximum Output Current – 500 mA) • 20 kHz PWM Output Frequency for MTD6501C/D and 23 kHz for MTD6501G • Boost Mode (Optional Back Electromotive Force (BEMF) Pre-amplification in MTD6501D) • No External Tuning Required Description The MTD6501C/D/G devices are 3-phase, full-wave drivers for brushless sensorless DC motors. They feature 180° sinusoidal drive, high torque output, and silent drive. Due to their adaptive features and wide power-supply range capabilities (2V to 14V), they are intended to cover a wide range of motor characteristics, while requiring no external tuning from the user. Speed control can be achieved through either power supply modulation or pulse-width modulation (using the PWM digital input pin). Due to the compact packaging and minimum bill of materials (power transistors incorporated, no Hall sensor, no external tuning), they are best suited for low- cost fan applications requiring high efficiency and low acoustic noise, such as CPU cooling fans. Frequency generator output enables precision speed control in closed-loop applications. The MTD6501C/D/G drivers include a Lock-up Protection mode, which turns off the output current when the motor is under lock condition, and an automatic recovery that enables the fan to run when the lock condition is removed. Motor overcurrent limitation, short-circuit protection and thermal- shutdown protection are also included. The MTD6501C and the MTD6501G are available in a compact thermally-enhanced SOP-8 package, while the MTD6501D is available in the MSOP-10L package. Package Types The MTD6501C/D/G devices are formerly products of Advanced Silicon.
